If the delay between a sound and its echo is less than 1/10th of a second, the human ear can’t distinguish it. Through the use of a Slinky, rubber band guitar, and straws, scholars explore where sound comes from and how it travels....

An activity tests the fluency skills of young readers. Scholars match initial sound cards to letter cards. Pairs take turns and work to locate the most matches before the timer goes off. The activity ends with a peer evaluation.

Explore how sound travels as waves with a straightforward lesson that explains the basics of waves in relation to sound. The presentation considers sound waves in both open and closed pipes and shows how to calculate wavelength and...

Should democracies include hate speech as a protected right? Scholars analyze the rights found under the First Amendment to the Constitution through researching evidence. Freedom of expression becomes the focal point of the...

In this waves activity, students use the equation for wave speed to calculate frequency or wavelength. This activity has 5 problems to solve.

In this speed of a galaxy activity, students use a given equation for the speed of an object and they use the spectral lines for Hydrogen Alpha and Beta from the Seyfert galaxy to answer 6 questions. They determine the observed...

Scholars time each other as they work through a sheet of all 26 letters. They test each other to see how many letters sounds they can identify in one minute.

Which travels faster, light or sound? Scholars work in groups to simulate the ability for waves to travel through solids, liquids, gases, and through a vacuum. Then, they learn about the properties of a mystery wave and must determine...

Young scholars spin their way to letter sound fluency. While tomes, pairs spin a spinner and make the sound of the letter on which it lands. They add a counter to their cup for each sound they make correctly. At the end of the game,...

A memory activity engages young learners in letter-sound correspondence. Pairs take turns examining two sets of cards lying face down. They flip one image card and one letter card, then name the initial sound. If the sounds match, pupils...

Students experiment with measuring the speed of sound in an open field by clapping hands and measuring the time delay between the clap and hearing the sound at a long distance. Students practice solving equations at completion of activity.

In this physics 210 learning exercise, students answer the question of the predicted modes of oscillations heard based on the information provided in the word problems. Students apply their understanding of sound waves to answer the...

Add a little music to your next physics class. Pupils discuss how frequency determines pitch and take part in several activities designed to teach them more about sound, melody, resonance, and vibrations. They use materials to construct...

Fifth graders explore and examine the basic properties of sound. In pairs, they speak through a balloon and listen to the sound vibrations, and listen to a ticking clock or watch through a variety of materials and identify the...

Students investigate the concept of velocity and apply it to the velocity of sound and measure the velocity of sound by measuring the echoes produced in a tube. They show their calculation of time and speed, and then conclude that sound...

Sixth graders use a laser along with computer microphone probeware and the appropriate software, 6th graders determine the speed of rotating objects.An audio amplifier is connected to a solar cell to change the laser light signal into a...

In this light worksheet, students read what makes light, the speed of light, and the electromagnetic spectrum. Students complete 12 matching, 8 fill in the blank, and 9 word problems.

You matter, unless you multiply yourself by the speed of light ... then you energy. Presentation covers the behavior of light as both a wave and a particle, light versus sound, space travel, why objects have colors, depth perception,...

Take a look at an organized physics course. The 34-section electronic textbook covers material in AP® Physics 1 and 2. Teachers use the text to supplement lectures and have the class work through the labs. Each section contains...

Conquer your fear of thunder and proportions. After viewing a video of lightning and thunder, scholars consider how far away the storm is from the recorder. This obviously requires the use of proportions and rates.

How fast can you go? Test scholars' letter sound recognition with a timed game. Using letter cards of all the letters you've learned so far, learners take turns flipping cards and correctly saying the letter sound. Model this first,...

Explore reading for fluency and speed with your class. They discuss reading faster, smoother, and with more expression. Practice reading with fluency using one minute timed reads. They read "Tin Man Fix-It." and record how many words...

In this acoustics activity, students use a chart of the speed of sound through different materials to determine which materials should be used to build certain building types. Students complete 2 short answer questions.

A well-designed, comprehensive, and attractive slide show supports direct instruction on how sonar and echolocation work. Contained within the slides are links to interactive websites and instructions for using apps on a mobile device to...
